Weatherproofing is at the forefront when it comes to door & window design

Our products are independently tested at accredited testing stations for extreme weather conditions.

Most systems on the market are weather tight, with high performance rubber seals and brush seals. However, there are some systems that have little or no seals at all. One crude but easy test is too close a folding door on to a sheet of paper and try to pull the paper out. If it pulls out easily there is not a watertight compression on the seals.


High Performance Seals

We use high performance rubber EPDM seals on every product

EPDM (ethylene propylene diene monomer (M-class) rubber) gaskets are fitted as standard and used to seal the double/triple glazed units into the frames and protect the doors & windows from water ingress.

There are also EPDM (synthetic rubber) seals between each bifold panel to prevent water, wind and noise from entering the property. The main properties of EPDM are its outstanding heat and weather resistance.

We use 2 rubber EPDM seals on each side of each bifold panel and high performance seals on the top and bottom of the panel.

Unique Tongue and Groove Feature

Our bi-fold door systems includes a tongue and groove feature unique to our bi-fold door systems which:

  • Prevents water infiltration
  • Keeps the system stable with one panel interlocking with another ensuring that the integrity of the system remains intact whether the doors are opening inwards or opening outwards
  • Prevents attack by an intruder

Exceptional Strength

The fusion of our glass fibers and polymer matrix GFRC thermal break and aluminium imparts exceptional strength and durability.

GFRC (Glass Fiber Reinforced Composite) thermally broken windows and doors are highly resilient against various weather conditions.

The integration of glass fibers into the composite material enhances its strength and durability, making it capable of withstanding extreme temperatures, strong winds, and heavy precipitation.

The thermal break feature is especially valuable as it effectively isolates the interior from the exterior temperatures, improving the thermal efficiency of buildings.

This combination makes GFRC an excellent choice for creating windows and doors that need to perform well in diverse and challenging climates.

GFRC vs Traditional Materials

GFRC thermally broken windows and doors offer numerous advantages when it comes to weather resilience.

When comparing weather resilience, GFRC thermally broken windows and doors surpass traditional materials like wood, aluminum, and uPVC:

Wood: Offers aesthetic appeal but is prone to warping and rot. GFRC Thermally broken options, like aluminum clad with wood, enhance strength durability and weather resistance.

Aluminum: Strong yet, unless thermally broken, it conducts heat, leading to poor insulation. GFRC thermally broken aluminum improves strength & thermal performance significantly over standard thermal breaks.

uPVC: Provides good insulation but lacks robustness and can warp or fade over time. GFRC thermally broken alternatives offer superior strength, durability and weather resilience.
